WILLIAM E. FOBES, OF GOSHEN, INDIANA.

MOLD.

To all 'whom it may concern.'

Be it known that I, VILLIAM E. FoBEs, a citizen of the United Sta-tes, residing at Goshen, Indiana, have invented certain new and useful Improvements in Molds, of which the following is a specification.

This invention relates to improvements in molds.

The main objects of this invention are:4

First, to provide an improved face plate or pallet for molds, the body of which is formed of concrete, which is comparatively light in weight, and, at the same time, very strong and is not likely to be broken in use, also one which is very durable. Second, to provide an improved face plate or mold which will impart to the article molded a natural cutstone appearance. Third, to provide an improved mold which can be readily set up and knocked down, and is particularly adapted for my improved face plate.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the :following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure l is a plan view of a mold embodying the features of my invention. Fig. 2 is a detail vertical section thereof. Fig. 3 is a detail perspective of one of my improved face plates or pallets. Fig. 4L is an enlarged detail transverse section thereof taken on a line corresponding to line 4-f of Fig. 3. Fig. 5 is an enlarged detail view showing the inside of the frame of my improved face plate or pallet. Fig. 6 is an enlarged det-ail view of a modified structure, the flange at the edge of the frame being absent. Fig. 7 is a perspective view of my improved face plate adapted for use. in the manufacture of' fractional blocks, as they are commonly termed. Fig. 8 is a detail section taken on a line corresponding to line 8--8 of Fig. 7

In the drawings, similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

cast within the frame 3. The outer side ofV the face plate is preferably a plain, fiat sur face, and fiush with the outer edge of the frame, while the inner side contains a suitable pattern which is suitably formed to produce the desired conformation of the blocks. The plate may be turned around when a flat faced block is desired. Thus the plate is adapted for forming two styles of blocks.

A binding strip 5 is preferably provided to assist in securing the body within the frame. This is preferably formed of reticulated metal, (the so-called expanded metal being shown,) the edges of the strip being secured by folding or clamping the edges of the body thereon, as clearly appears from the drawing. This binding strip is prefer* ably bowed out in cross-section, as illustrated, so that it is effectively embedded in the body 4. It would, however, assist in retaining or binding the body within the frame if it was laid flat on the frame.

The mold illustrated in Figs. l and 2 consists of a bottom or base plate G, and a rectangular face plate supporting frame 7. This frame is supported in an elevated position above the base plate by the rests S. The face plates are arranged on edge on the base within the frame, one pair of face plates resting against the frame and the other being supported by means of the wedges 9. The face plates are preferably provided at their ends with projecting lugs 10 adapted to engage the adjacent face plates. These lugs hold the face plates in proper relation to each other and the fra-me, and the full face of each plate is brought into position. The inturned flanges 8 of the frames form a smooth edge or border line for the block, which further enhances the appearance of the block. This border, where desired, I sometimes form in the concrete body of the block. The core 1l is preferably a block of wood having a handle 12 for convenience in handling. When it is desired to knock down the mold for releasing the block, the core of wood is removed and the wedges 8 thebloclrs on after they are molded. Y

Ywrelnovelfl.V This releases theframe'so that it f edges ofthe frame;

^ Y pallets in use..v yThey are, however, adaptedv can be lifted ff and the face plates or side walls of the'mold are all released.

In Figs. 7'and'8, the structure is shown having a channel cross`piece13 thereon, the edge of the cross-piece being flush with the The structure is thus adapted to receive a partition plate or the like. Y Y

-. 'f -The mold illustrated Vshows one` means of supporting my Vimproved face plates or for use in various relations with various forms of molds and eitheras face plates or pallets,-that is, kthey may be `used to dry f j My improved 4 face lplate is very econom- V ical to produce, comparatively light in weight, and is very durable and not likely to bel broken rfrom ordinary usage, and its edges are so protected that t-hey cannot-be V 'chipped off, thereby disguring 'the blocks molded therewith or rendering the face plate or pallet useless.

Having thus described my inventiomwhat I claim as new and desire to secure by'Let# ters Patent is: N1.' Astructure of the class described, com- Y pri'sing a band-like metal frame having `Y reticulated strip arranged and secured withinwardly-projecting flanges at its edges; a

in said frame by clamping the said inturned y flanges of said yframe upon its edges, said binding strip being bowed inwardly; and a body of concrete molded into said frame, the

outer 'side of said body being Hush with the outer edge of .the frame and the inner side f being suitably conformed.

Y 2. A structure of the'clas'sdescribed, comrisino` va metal frame havin inwardl royjecting fiangesat its edges; -a reticulated strip arranged 'and n secured within said frame `by clamping the said inturned flanges of said frame upon its edges, said binding strip being bowed inwardly; Yand a body of concrete molded into said frame.`

3. A structureof the class described, comprising'a band-like metal frame; a reticulated strip arranged and secured within said frame byY folding thev edges of said frame strip arranged and secured within said `frame by folding the edges of said frame upon its edges, said binding strip being bowed inwardly; and a body of concrete molded into said frame.

5. A structure of the class described, co1nprising a sheet metal frame; reticulated `binding strips arranged withiny said frame parallel with the side and end pieces thereof, the edges lof said frame being folded inwardly upon the edges of said binding strips, whereby they arev retained in position in said frame; anda body of concrete molded into said frame upon said binding strips.

6.7In a structure of the class described, the combination with a base of a frame; restson said base for said frame; side walls arranged in said frame, said side Walls hav- Ving lugs at their ends adapted to engage the ends of the adjacent walls; oppositely disposed wedges for supporting one pair of said side walls, and a removable core plug.

7. In a structure of the` class described, the combination with a base of a frame; rests on said base for said frame; side walls arranged in said frame, said side walls'having lugsat their ends adapted to engage'the ends of the adjacent walls; and oppostely disposed wedges for supporting one pair of said side walls.

- In witness whereof, I have hereunto set my hand and seal in the presence of two witnesses.
